The oceans are smoking and the bad news is that that phrase is starting to stop being a metaphor

by

Global sea surface temperature is once again approaching 2024 records, Arctic ice marks its historic winter minimum and the average temperature is 1.43 degrees above pre-industrial levels. What’s more, the Earth’s energy imbalance has reached its highest level in 65 years. And all of this without El Niño being active. So I have to correct myself: what is happening is not that the sea is smoking. That’s a huge understatement. What happens is that the oceans have gone up a notch and we are completely caught out of the game. What is happening? According to Copernicus dataIn March, the global average temperature was 13.94 degrees. That is 0.53 above the 1991-2020 average and 1.48 above the pre-industrial temperature. It’s not the warmest March on record, but it’s close. In contrast, February 2026 was one of the three coldest in the last 14 years. And it’s curious because, anyway, we are in ENSO-Neutral conditions. The 2024 record was reached with El Niño pumping heat from the Pacific; Now we are in the most absolute normality. That does have experts from half the world worried. And the sea? In the sea things are more complicated because the surface temperature is very close to lrecord ace of 2024. Furthermore, it is not a question of a specific rebound: it is the result of a sustained rise throughout the entire month of March. There are specific areas (subtropical and northeastern North Atlantic, North and South Pacific) that are already at record values; The big question is what will happen at the end of the year and, above all, at the beginning of the year when El Niño is at its highest peak of intensity. Well, but this doesn’t affect us much, right? It depends on what we mean by ‘affect’, of course. What there is no doubt is that, despite the fact that temperatures are rising around the world, the Mediterranean has become the great laboratory for all detected and undetected climate risks. After all, Mare Nostrum heats up to 20% faster than the global average. And that has clear and direct consequences for water: from the mass extinction of vertebrates to the decline of grasslands to an enormous mortality of fish. Is a sea dying little by little; a sea that drags us with it: because the heat of the Mediterranean injects more water vapor and fuels extreme precipitation phenomena. The DANA of Valencia It’s a reminder of all this.. That is, the scenario is known. What remains is to see what we do to prepare for it.

James Webb has bad news for the largest natural laboratory for rocky planets, but there is still some hope

by

The star TRAPPIST-1 and the seven known planets that surround it are a natural laboratory in which the evolution of rocky planets can be studied. This has led many scientists to focus their attention on them, in search of a possible habitable planet. However, observations made by an international team of astronomers with the help of the James Webb Space Telescope They are not very encouraging. Planets without atmosphere. The James Webb Space Telescope has a very powerful infrared radiation analysis instrument, with which it can analyze the temperature of the planets it observes. These emit infrared radiation whose intensity is proportional to their temperature, so a thermal map can be made. That’s what these astronomers have done. They have initially focused on two of the planets that orbit TRAPPIST-1: TRAPPIST-1a and TRAPPIST-1b. The resulting heat map shows that neither planet has an atmosphere. They may have had it one day, but possibly TRAPPIST-1 itself destroyed it. It is a very uninspiring result for the search for habitable planets in this system. Lights and shadows of TRAPPIST-1. So far seven exoplanets have been discovered orbiting TRAPPIST-1. They are all very close together. In fact, its seven orbits are concentrated in the distance between Mercury and the Sun. What happens is that this red dwarf is less energetic than our Sun, so the temperature would not be as suffocating. All of these planets are rocky, like Earth, and in fact, some are very similar in size. There could be an exoplanet with conditions similar to ours. The problem is that red dwarfs They emit a lot of radiation and energetic flows of particles that could destroy their atmosphere.. And of course, without atmosphere, there is no life. Tidal lock. All planets in the TRAPPIST-1 system are tidally locked. This means that its rotation and translation period around the red dwarf they are synchronized. As a result, there is one side continuously exposed to the star and another on the opposite side. On one side it is always day and on the other it is always night. NASA/JPL-Caltech Extreme temperatures. When a planet is tidally locked, there can be two situations, depending on whether it has an atmosphere or not. When there is an atmosphere, heat flows from the light side to the dark side, so that the entire planet has a stable average temperature. On the other hand, if there is no atmosphere, the dark side can be frozen and the illuminated side can be scorched. In the two exoplanets analyzed by James Webb, it has been seen that temperatures are around 100ºC-200ºC on the illuminated side and -200ºC on the dark side. Therefore, it is confirmed that there is no atmosphere. And now what? Despite this hard blow, there is still hope. The two exoplanets that have been analyzed are not in the star’s habitable zone. This is the distance from it at which the temperature is adequate for the water, if any, to remain in a liquid state. At that exact point there are only TRAPPIST-1e, TRAPPIST-1f and TRAPPIST-1g. Furthermore, the former has a density and size very similar to those of Earth. James Webb has all his attention on this exoplanet right now, to repeat the process. If there were an atmosphere on it, it could still remain on the list of possible habitable planets. It’s still interesting. Despite the first blow, TRAPPIST-1 remains a very interesting system for understand the evolution of rocky planets. The Earth was lucky not to lose its atmosphere; but, beyond those, the evolutions can be similar. Furthermore, we have not yet ruled out that TRAPPIST-1e has an atmosphere. Let’s go step by step.

We already know where many of the microplastics that enter our body end up. We have bad news

by

That microplastics had managed to enter our body is something that we already knew in detail, especially considering that we have found them in the lungsin the placenta and even in the testicles. However, there were questions about where they accumulated in greater quantities in our body and what consequences does it have. Something that science has already solved. What they have seen. It has been thanks to a recent study published in the journal Environmental Science and Ecotechnology that it has finally been revealed that not only can cholesterol crystals be found in bile that end up generating stones, but also there are microplastics. And the worst of all is that they have a direct impact on the premature aging of the cells that make up our gallbladder. How do you know? To reach this conclusion, the researchers analyzed 14 samples of human bile: five from healthy patients without gallstones and nine from patients with gallstones. The results were conclusive, since they found microplastics in the samples, mainly highlighting two of them. the most common polymers in our daily lives: polyethylene (PE) and polyethylene terephthalate (PET). Here it could be seen that the particles had a size that ranged between 20 and 50 micrometers. A very relevant fact, since from these sizes is when they can cross the biological barriers, cross the intestine-liver axis and end up in the gallbladder of our liver. There is more. In addition to the presence of plastic in the bile, it could be seen that patients who had gallstones showed a higher load of microplastics. Something fundamental, since it is a fact that fits with recent research that suggests that these particles could act as ‘seeds’ around which cholesterol groups to form the dreaded stones in the gallbladder. What do they do? This is the key point of these studies, since we still do not have much idea of ​​the damage that microplastics can do to our body. Here it points out that bile causes mitochondrial dysfunction and promotes the aging of cholangiocytes, which are the cells that line the bile ducts. In previous experiments, it was possible to see that in the liver of laboratory mice exposed to environmental concentrations of microplastics there was alteration in the metabolism of bile acids and liver damage. In the case of humans, which increases oxidative stress. But the important thing is that in both cases the bile duct cell loses its ability to function correctly and ages prematurely, which in the long term could be related to liver and bile duct diseases. Can it be mitigated? Among the bad news, scientific literature suggests that there are ways to avoid it. One of the great protectors that exists is melatonin, suggesting that it can combat oxidative stress and mitochondrial dysfunction generated by these synthetic intruders. In parallel, other recent experiments with human liver organoids have shown that the damage caused by microplastics improves when ursodeoxycholic acid is administered, which is the drug administered to ‘dissolve’ gallstones. The ‘magic’ of this compound is that it increases bile flow, suggesting that promoting a kind of natural “washing” of the bile duct could help reduce toxicity. A problem. The confirmation of bile as a “hidden reservoir” of microplastics highlights an undeniable reality: plastic pollution is no longer just an environmental problem in our oceans, but a systemic public health problem about which we know more and more data. The longer-term consequences, such as the relationship with gallbladder cancer, remain to be seen.

There is a way to open the dishwasher incorrectly. This is bad news for your kitchen furniture.

by

Practically half of Spanish homes have a dishwasher. And some of the most reputable manufacturers have had to come to the fore to explain why. it’s not a good idea Open the door as soon as the washing cycle ends. Don’t be craving. Opening the dishwasher as soon as the wash cycle is finished is not the best idea, according to the manufacturers themselves. Some, like Boschrecommend waiting for it to cool a little before opening the door so that less steam comes out of the opening. Others, such as Siemens, make exactly the same recommendation: let the appliance cool down slightly after the program ends before opening the door. Because. Opening the dishwasher at the end of the cycle is not particularly dangerous, but it can cause problems in your kitchen in the long term. Manufacturers point out that excess steam when opening the door when it is still quite hot can end up damaging kitchen furniture. Similarly, dishwashers use their own residual heat to help the correct drying process. All this without taking into account the most obvious detail: if we open the appliance when it is full of high-temperature steam, we run a greater risk of suffering a slight burn. How the dishwasher works. To understand why the dishwasher generates so much steam at the end of the cycle, it is worth doing a brief review of how it works. Basically, it is a closed circuit that allows hot water to be pumped into rotating arms. When you choose the program, the door closes. Water enters its base and the dishwasher heats it. When the water is hot, the pump pushes it under pressure into your arms. The water hits the dishes and drags away the dirt. The detergent is released and begins to break down grease and food debris. The residual heat dries the dishes little by little. The heat problem. Aware that opening the dishwasher as soon as it is finished is common practice in homes, manufacturers have been devising solutions for years to prevent excess steam. Some appliances of this type have an automatic opening system. The door opens just a few centimeters to let the steam out little by little, so that when we finish opening it manually we avoid that initial blow. Other systems, even more advanced, they use zeolites. Zeolites are microporous aluminosilicates (of mineral or synthetic origin) that have a crystalline structure with a huge internal surface area. When they absorb water molecules the process is exothermic, that is, they release heat. This allows part of the steam to be collected and used as waste heat for drying. Increasingly advanced solutions to address a problem as simple as it is common. In Xataka | A user bought a next-generation connected dishwasher. That’s where his nightmare began

SpaceX is now a company in the railway sector and it is very bad news for its employees

by

For some people it will be ingenuity, for others a very hard face, but the point is that SpaceX has found a way to avoid lawsuits and strikes by its workers when obtaining the name of air transport company. This means that it is regulated under the Railway Labor Law, with all the benefits that it entails within US legislation. The news. On March 13, the official resolution was made public by which SpaceX, Elon Musk’s space agency, is now considered a company in the railway sector in the United States. This means that your activity is no longer subject to the supervision of the National Labor Relations Board (NLRB)which is typically responsible for protecting the labor rights of private sector workers. The layoffs that started it all. In January 2024, the NLRB put a lawsuit against SpaceX on the tableafter the company illegally fired 8 employees. The lawsuit requested reinstatement of the employees, back pay, and a letter of apology to each of them. Given this situation, SpaceX responded with another lawsuit to the NLRBalleging that the procedure being carried out was unconstitutional. Rockets have the same legal treatment as cargo planes. An ace up your sleeve. According to Elon Musk’s company, the NLRB should not be able to act against a company that is dedicated to transportation. He added that One of its main missions is the transport of humans and goods to the International Space Station.. In many cases, these jobs are carried out for NASA, so they would also be providing a service to the Government. For all this, they requested to be covered under the Railway Labor Law. A plan that suits many. In recent years, SpaceX, as well as other Elon Musk companies, have been the subject of complaints from a multitude of dissatisfied employees, either due to their personal situation or due to bad practices carried out in the company. In the case of Neuralink, for example, Very bad practice towards laboratory animals was reported. But returning to SpaceX, the increasing volume of complaints could put the company’s work pace at risk. This, logically, would harm its managers, but also the companies that benefit from its services. The entire US space program would probably collapse. For all this, although it seemed difficult, in the end Elon Musk’s company has had a resolution in favor of its new name. Immune to strikes. One of the peculiarities of railroad companies in the United States is that they benefit from special state protection. Since minimum transport services must be guaranteed, strikes and other similar activities that would normally slow down the normal pace of work are closely controlled. The NLRB no longer rules. Another of those special protections for railroad companies is that the NLRB no longer has power over them. Therefore, dismissed employees cannot resort to it to report their situation. Instead, the company is governed by the rules of the National Mediation Boardmuch more lax in the mediation of labor disputes. It is true that employees can request strikes, but to do so they must undergo a long and tedious process that often causes them to change their decision. And now what? With this new name, SpaceX has even more power and freedom than before. If measures are carried out that involve malpractice towards employees, it is difficult for their complaints to come to fruition legally. This gives them a lot of leeway and greatly speeds up their protocols. Other curious legal victories. It is not the first time that SpaceX has obtained an unexpected legal name. Last year, for example, The Starbase base was given the name of cityso that all employees who live nearby would also become inhabitants. This, far from changing a few patterns, also gave SpaceX more freedom when maneuvering in the areas surrounding its base. As with railway legislation, what may seem like a small name change can change everything.

The good news is that the Ebro reservoirs are at a historic 85% water level. The bad thing is that we are going to spend it in a short time.

by

There are 6,640 hm3 of water in the Ebro basin. The reservoirs are at 85.1% of its total capacity at what is its highest level (for this date) of the decade. And yet, the fact that there is a lot of water is not news. All of Spain is the same (83.3%). The news is that we are going to spend it. A structural problem called ‘Mediterranean’. Every year, the pressure of the Mediterranean summer and the irrigation campaign empty the reservoirs very quickly. AND, as history has shown usthere is never too much water: “each dry period has served to implement emergency measures for agriculture that were not eliminated when the rains returned, they were used to expand irrigation, aggravating the problem in the following drought”, said Ana Tudela and Antonio Delgado. And that, precisely that, is what we are about to see. The complete image. Seeing the figures for the reservoirs can lead us to forget that, just three years ago, 85% of the basin’s surface was in “prolonged drought“and 45% of them declared themselves in shortage emergency. Mequinenza, the largest swamp, reached historic lows. It was a catastrophe not only in water terms, but also in energy terms. Now, however, all that is in the past. And Say’s Law lurks in the dark. What the old French economist Jean-Baptiste Say argued at the end of the 19th century is that “every supply creates its own demand“and, translated into this situation, this means that the fact that there is more water generates all the incentives in the world for there to be more irrigation. As soon as we do it, this becomes clear. After all, not all of the basin’s storage capacity is enough for a full year of agricultural demand. Without the annual rainfall and the melting of snow, we could already consider all its reserves exhausted. March is the key month. The irrigation campaign runs from April to September and that means that March is the key month for planning the year. It is true that the thaw has not yet begun (which this year is going to be very intense), but it helps us estimate what quantities of water are really available. All irrigated agriculture in the valley depends on the water we are able to store during the spring. The question from now on becomes: how do we conserve as much water as possible before we once again enter a situation of risk? And the problem is that we don’t have answers. Especially in a regulatory context in which are not foreseen widespread restrictions on irrigation. Economic, social and institutional incentives tell us that we are not yet prepared, as a country, to address the really important question: we do not have a water problem, we have a consumption problem. There is still room for improvement in management, yes. But that won’t solve the problem: it only postpones it. And that 85% of reservoir water has given us unbeatable weather, we just have to hope that we can take advantage of it.

Japan has taken a look at the data after the disappearance of thousands of Chinese tourists and it has been said that it is not so bad

by

In the recent tourist chronicle of Japan there is a date marked in red. November 7, 2025. That day the prime minister Sanae Takaichi opened the box of thunder announce that Tokyo would not hesitate to deploy its troops in case China invaded Taiwan. The statement fell like a bucket of cold water on Beijing, which further made clear its discomfort at the diplomatic level, asked its citizens to avoid traveling to the country of the rising sun. Taking into account the enormous weight of Chinese visitors in Japanese hotels, that it sounded like a catastrophea punch in the gut for its thriving tourism industry. Well not so much. The latest data of the Japan National Tourism Organization (JNTO) show that this is not the case. It is true that the country receives fewer (much fewer) Chinese visitors than a year ago, but the gap they have left in the hotels has not taken long to be filled by clients from other nations, especially from Asia. A percentage: 6.4%. February has been a good month for the Japanese tourism industry. At least as far as the arrival of travelers is concerned. He last balance from JNTO shows that throughout the month the flow of visitors grew by 6.4% compared to the same period in 2025. From 3.26 million it went to 3.47. The accumulated of the first two months of 2026 is also positive. Japanese tourism now totals around 7.1 million visitors, 0.3% more than last year. Said like that it doesn’t seem like a big deal. The weakness of the yen and its enormous popularity in networks, added to the recovery of the international tourism market after the pandemic stop, have turned Japan into everything a tourist phenomenon. One on a roll and accustomed to record numbers. In 2025, without going any further, the country will receive 42.7 million of foreign visitors, a historical mark that places the nation above 40 million for the first time in its history. So… Why is it news that it rose 6.4% in February? Why does that percentage matter? Countries February 2026 Evolution (%) Accumulated 2026 Evolution (%) TOTAL 3,466,700 +6.4 7,064,200 +0.3 South Korea 1,086,400 +28.2 2,262,400 +24.7 China 396,400 -45.2 781,700 -54.1 Taiwan 693,600 +36.7 1,388,100 +26.1 Hong Kong 233,900 +19.6 433,900 -1.2 Thailand 117,000 +0.2 232,100 +8.7 Singapore 51,300 +21.4 99,800 +13.4 Malaysia 59,700 -8.0 132,200 -5.5 Indonesia 51,200 +8.9 125,200 +13.6 Philippines 71,700 +7.5 150,900 +8.7 Vietnam 61,000 -17.4 113,800 -8.4 The answer: China. What is surprising is not that Japan continues to receive more tourists. The surprising thing is that it does so despite how much the Chinese market, one of its pillars, has become very complicated. We mentioned it before. Takaichi’s statements in November in which he implied that Japan would not sit idly by if Beijing forced its way into Taiwan caused an earthquake that jumped from diplomacy to the economy and from this directly to tourism. As part of their response to punish Takaichi, in mid-November the Chinese authorities they advised its citizens not to travel to Japan. They were even canceled dozens of flights and they refunded plane tickets. From politics to hotels. It didn’t take long for the boycott to be noticed in Japanese hotels. If the flow of Chinese tourists grew at 22.8% in October 2025, the following month (after Takaichi’s speech) that percentage had deflated to 3%. In December it went directly into the red, with a drop in 45.3% which was expanded to -60.7% in January. In February (latest JNTO data available) the balance again marked another puncture of the 45.2%confirming the trend. The percentage is better understood when talking about people: between January and February Japan received 921,700 fewer Chinese than in the same period in 2025. And the alarms went off. The problem is not only the drop in visitors, which is already alarming in itself. If the Japanese sector began to worry, it is because China represents a strategic market. And doubly so. To begin with, it is because of its weight. Along with South Korea, the Asian giant is the main fishing ground for visitors to Japan. In 2025 it added 9.1 million tourists21% of the total. Only South Korea mobilized more. And the data only reflects mainland China. Travelers from Hong Kong (another big market) go separately. The other reason why the Asian giant is so important for Japanese businesses is the profile of its tourists. Not only do many travelers leave China, those who pack their bags to spend their vacations in other countries also do so with full wallets. JNTO itself calculate that last year Chinese tourists spent about 25% more than other travelers during their stays in Japan, something that is especially noticeable in shopping centers. After Takaichi’s words about Taiwan (and the diplomatic storm between Tokyo and Beijing) there were businesses in the sector that they recalculated their forecasts billing, assuming double-digit drops in its earnings estimate. In the absence of Chinese… Other markets are good, which is what the JNTO statistics reflect. Despite the initial fear that Beijing’s boycott would hit Japanese tourism, slowing its unstoppable growth streak, Japan has managed to rebalance the sector. After experiencing a overall flow drop of visitors of 4.9% in January, last month that percentage was corrected and the industry grew again. In total in February they visited Japan about 3.5 million of tourists. How is it possible? This increase actually has little mystery. The JNTO tables show that the 45.2% drop in the influx of Chinese tourists has been offset by an increase in visitors from other nations. The flow of South Koreans shot up, for example, by 28.2%, that of visitors from Hong Kong by 19.6%, that of Singaporeans by 21.4% and Indian tourists by 22.7%. Ironically (or not) one of the markets that has grown the most is Taiwan. Throughout February, 693,600 tourists from the Asian island visited Japan, 36.7% more than in 2025. This is relevant data because Taiwan … Read more

China already has two chip manufacturers with 7nm technology. This is very bad news for the US and its allies.

by

SMIC (Semiconductor Manufacturing International Corp), the largest Chinese semiconductor manufacturer, has the capacity to produce 7nm chips from 2023. At the beginning of September of that year this company shook up the integrated circuit industry by demonstrating that it had been able to manufacture these semiconductors despite not having access to UVE photolithography equipment (extreme ultraviolet) produced by the Dutch company ASML. These highly sophisticated machines are necessary to manufacture cutting-edge chipsand ASML cannot sell them to its Chinese customers because the US, which controls some of the patents used by this equipment, prohibits it. Still, in 2023 SMIC and Huawei worked hand in hand to manufacture 7nm ICs without using ASML’s EUU machines. Of course, they used deep ultraviolet (UVP) equipment that this company from the Netherlands also produces. UVP machines are not as advanced as UVE machines, but with proper refinements they can be used to manufacture cutting-edge integrated circuits. And now China has two semiconductor manufacturers capable of producing 7nm chips. As we have just seen, one of them is SMIC, and the other, according to Reutersis Hua Hong Semiconductor, the country’s second largest integrated circuit producer. The shadow of ‘multiple patterning’ is very long Hua Hong Semiconductor’s division specializing in third-party chip manufacturing is called Huali Microelectronics, and, again according to Reutersis preparing to start production of 7nm integrated circuits at its Shanghai plant. The sources that have revealed this information assure that Huawei has collaborated with Huali Microelectronics on this project, which invites us to reach two reasonable conclusions. It is very likely that with the help of Huawei, Huali has developed ‘multiple patterning’ techniques The first is that Huali’s 7nm lithography will most likely play an essential role in GPU production capacity for artificial intelligence (AI) from both Huawei and other Chinese companies. And the second conclusion is actually a plausible hypothesis. And, like SMIC, Huali does not have access to ASML SVU equipment. For this reason, it is very likely that with the help of Huawei it has developed security techniques. multiple patterning to be able to manufacture 7nm chips with the UVP machines in its possession. A priori, UVP machines are suitable for manufacturing semiconductors up to 10 nm. And with EUVs it is possible to exceed 3 nm. However, by refining the processes involved in transferring the pattern to the wafer and turning to multiple patterning It is possible to go beyond these integration technologies. This technique broadly consists of transferring the pattern to the wafer in several passes with the purpose of increasing the resolution of the lithographic process. It may have an upward impact on the cost of chips and a downward impact on production capacity, but it works. Either way, Huali Microelectronics is going to face the same challenges that SMIC has dealt with for the last three years: the multiple patterning seriously limits the number of viable chips per wafer that is possible to manufacture. And, therefore, it increases its cost. Still, it is very important for Chinese AI chip designers to have access to two companies capable of producing their designs with advanced photolithography technology. And for Hua Hong Semiconductor it is crucial to have the ability to manufacture, thanks to Huali, cutting-edge integrated circuits and not just 22 nm or larger (this is the most advanced photolithography it had so far).

For the first time, BYD has sold more cars outside of China than inside. It’s very bad news for them.

by

Pursue your dreams… outside of China. Beyond Your Dreams are the words hidden behind the acronym BYD. The acronym of the company that sold the most electric cars in the world in 2025. A company that seemed to have meteoric progress but that has stagnated with a local market that is slowing down at a dizzying pace. So much so that it has already sold more cars outside of China than inside. A well-thought-out strategy that arrives ahead of time. A milestone?. The month of February was the first in which BYD has sold more vehicles outside China than in its own market. It is a conditional milestone, since sales in China of the entire market have plummeted and, of course, have hit the country’s largest car manufacturer hard. A general trend. Although in 2025 car sales in China once again set a record with 34.4 million cars sold (a growth of 9.4%, according to the Chinese Association of Automobile Manufacturers) in figures collected by the media 36krthe market has been experiencing a slowdown for months. In February, car sales in the country fell 15% compared to the same month in 2025, they point out in Reuters. But the problem is worse among individuals, where sales have fallen by 34% as a result of the Chinese New Year festivities and the withdrawal of some purchasing aid. The latter has had a direct impact on sales of “new energy” cars (plug-in hybrids and electric). According to data collected by CNEVPostIn January, 596,000 cars of this type were purchased, compared to 744,052 units in the same month of 2025. A drop of 22.1% that worsened in February, with 464,000 units sold compared to 686,000 units the previous year. It is a year-on-year drop of 32%. The BYD case. This general decline in sales, with more worrying figures among new energy vehicles, has had a direct impact on BYD. Last January, BYD sold 210,051 new energy cars when in the same period of 2025 it placed 300,538 units on the market. In February, the figures were worse with 190,190 units sold compared to last year’s 322,846 units, reported in CNEVPost. That is, so far this year, its sales have fallen by 30% in January and 41% in February, extending a trend of low sales that has been going on since September of last year. BYD sales have not grown in China since June 2025. In July and August they achieved a technical tie in the year-on-year comparison but, since then, they have lost in all one-year comparisons. These falls have caused Geely to surpass BYD in sales in the first two months of the year. Between January and February, Geely has sold 476,327 units, just 1% more than in the same period of the previous year. There are just over 76,000 units than BYD (400,241 vehicles between January and February) thanks to a larger product portfolio and less dependence on “new energy” vehicles. This has avoided a fall due to the withdrawal of state aid, they state in SCMP. More outside than inside. As we said, BYD’s sales have plummeted in China but its exports have skyrocketed abroad. This has meant that the company has sold, for the first time, more cars outside its borders than within its borders, they point out in Electrive. Two factors explain it 41% decrease in sales in China compared to February 2025 Increase in exports of 50.1% compared to February 2025 The company has managed to consolidate sustained growth in its exports. They point out in CarNewsChina which with February now adds up to four consecutive months exporting more than 100,000 units. This has caused them to place outside their borders this month 100,600 units of the 190,190 units which have sold all over the world. That is, more than 50% of its sales have been delivered outside of China. a mirror. BYD has become the best example of what the Chinese market is all about. The country lives in a whirlwind of launches and a suffocating price war. BYD itself, with its new launches at ultra-competitive prices, has caused their own cars become obsolete with months on the market, gathering dust in dealerships. The rest of the companies have also played to lower prices to keep up the pace and release news at a frenetic pace, but that produces some anxiety in the client that sees how what is new today can be left behind very soon. Bad news in a country like China that has been trying for years to promote domestic consumption to put its economy into higher gear. But, in addition, the State has withdrawn some aid to the purchase of electric cars, the most important column in the industry. This has its consequences in the drop in sales among individuals. Before time. That BYD intended to expand outside China was no secret. In fact, his plans happened because half of global sales will be consolidated outside of China in 2030. The expansion plan with the factory Hungarythat of Türkiye and, it is rumored, another in Europe is part of it, without forgetting the Thailand and Brazil. The question is to know if this surprise of sales abroad has arrived too soon and the only thing it confirms is the slowdown that the brand will have to deal with in China. If you want to consolidate yourself as one of the largest global manufacturers (there was talk of reaching 5.5 million units in 2025 but finally they stayed below the 5 million border) it is essential that they expand borders and not depend solely on the internal market. European manufacturers can give BYD some examples of what happens if you base the bulk of your strategy on selling in China.

The good news is that AI models are becoming more powerful. The bad thing is that everyone ends up saying the same thing.

We have artificial intelligence. What we don’t have is artificial diversity. That is the conclusion reached by a group of researchers who did a relatively simple test: they asked 25 different AI models a bunch of questions to see what they answered. And that’s the bad thing: who answered things that were too similar. “Artificial hive mind”. Scientists from the University of Washington, Carnegie Mellon University and Stanford University, among other institutions, have published an interesting joint study. In it they reveal how after various tests it seems clear that although AI models are becoming more and more advanced, the problem is that they all seem to have developed a kind of “artificial hive mind”: no matter what you ask them, they answer in a suspiciously similar way. When asking all these models “what time was”, many responded with the phrase “time is like a river”, while another group of models answered that “it is like a weaver”. time is a river. One of the questions asked of these models is “What is time?”and although that question leaves clear room for very different answers, the worrying thing is that they were not. Several models responded with the phrase “time is a river” and then developed it a little, while others responded with “time is a weaver (of moments).” That similarity when it came to responding turned out to be a constant. The illusion of abundance. We believe that when we consult something with an AI we access a whole world of conversational possibilities, but the study reveals that in reality we are facing a system that proposes very similar outputs. Although language models promise limitless creativity, they tend to converge on that hive mind where diversity is sacrificed for statistical consistency. It is reasonable, especially considering that large language models They are based on the concept of transformera probabilistic system that tries to find the next “best” word as it answers us. Same script. The researchers created a large-scale data set with 26,000 queries from real users that theoretically allowed the models to generate multiple valid and creative responses. They called that data set “Infinity-Chat” and divided the questions into six main categories and 17 subcategories. IA, you repeat yourself more than a broken record. During the tests it was observed that the same model tends to repeat itself, generating very similar responses. In fact, even when special parameters were used for questions designed to encourage diversity, the same effect was produced. This is what researchers call “inter-model collapse.” Too similar. These tests made it clear that the semantic similarity, how similar the responses of the different models were, was worrying. According to the study, this similarity ranged between 71% and 82%, and in some cases certain models managed to generate identical paragraphs word for word. The training problem. It is not only that they all generate text in a similar way due to their design, but there is also a training problem. The authors suggest that this homogeneity of responses could be due to several reasons: Training data sources end up being shared: models They are trained with similar “datasets” and for example they are based on similar texts and knowledge that come, for example, from Wikipedia or a very similar set of books. Contamination effect due to synthetic data generated by other AIs: they also use synthetic texts generated by other AI models. Rewards: The models used to reward these models are calibrated to reward some notion of “consensus” quality. Thus, creative and individual diversity is punished. AIs are “educated” to be precisely very similar to each other. Problem in sight. All of this makes researchers explicitly warn about two clear risks when using these AI models. We will think the same: if we users do not stop using AI models that answer basically the same thing, our own ways of thinking on those topics and problems will be “homogenized”and it will also make our responses more uniform. Point of view reduction: The other danger follows from the first: if the AI ​​ends up converging and answering the same thing, points of view are eliminated. Here the biases for example from the western world will be evident in Western models (ChatGPT, Gemini, Claude), and the same will happen with the oriental ones, for example. This would cause the potential suppression of alternative worldviews, of perspectives and “looks” that are different from our reality.
